Product Details
Key Features
Documentation

The advanced PWM controller, FAN501, simplifies isolated power supply design that requires CC regulation of the output. The output current is precisely estimated with only the information in the primary side of the transformer and controlled with an internal compensation circuit, removing the output current-sensing loss and eliminating external CC control circuitry. With an extremely low operating current (250 µA), Burst Mode maximizes light-load efficiency, allowing conformance to worldwide Standby Mode efficiency guidelines. Compared with a conventional approach using external control circuit in the secondary side for CC regulation, the FAN501 can reduce total cost, component count, size, and weight; while increasing efficiency, productivity, and system reliability.

YG GROUP (YUGUANG INTERNATIONAL(HK)CO.,LTD) supports reliable sourcing through quality controls and compliance documentation. Please confirm product requirements, applicable certifications and supporting documents before ordering.

  • 1. Certification Scope: Quality certifications apply only to the entities, sites and activities listed in valid certificates. Management system certification does not certify each individual product.
  • 2. Product Authenticity: Products must match the agreed manufacturer, part number and condition. Supplier screening and authenticity checks help reduce counterfeit risk.
  • 3. Inspection & Testing: The inspection scope follows product risks and agreed requirements. Additional testing, laboratory arrangements, costs and lead times require written confirmation.
  • 4. Traceability & Documentation: Request conformity certificates, traceability records or test reports before ordering. Document availability, issuer and coverage must be confirmed for the offered goods.
  • 5. Environmental Compliance: RoHS and REACH information is based on applicable manufacturer documentation. Confirm the exact part, declaration date and relevant exemptions before ordering.
  • 6. Handling & Protection: Handling, storage and packaging follow applicable product requirements, including ESD and moisture protection where required. Special handling requirements must be agreed before ordering.

Product FAQ
Purchasing FAQ

What type of component is FAN501, and what package does it use?

FAN501 is an authentic electronic component manufactured by onsemi, categorized under Power Management ICs. It is supplied in the standard manufacturer-specified package footprint, providing industry-standard mechanical dimensions and terminal configurations for board-level assembly. Full pinout configurations, physical footprint drawings, and rated operating tolerances are documented in the official FAN501 datasheet above.

Why is pricing for FAN501 available via RFQ rather than a fixed checkout price?

Electronic component spot-market pricing for FAN501 fluctuates based on real-time global availability, production date codes, minimum order quantities (MOQ), and packaging formats (e.g., Reel, Tube, Tray). Using an RFQ ensures you receive accurate, real-time volume pricing tied to verified, traceable inventory rather than stale catalog estimates.

How quickly can FAN501 be shipped once quoted?

Lead times for FAN501 depend on whether stock is dispatched from our central hub or regional franchise partners. Ready-to-ship inventory typically leaves the warehouse within 1–3 business days following quality inspection, while factory-direct or back-ordered allocations are confirmed with an estimated ship date upon RFQ reply.
